1 ALBERT A. sTELriNG', oFMAlfnso-N, wisconsin, AssreNoR TOTHE MADISON KIPP LUBRIcATon COMPANY, on MAnrson,Wisconsin'y f* A CORPORATION. i

n Be a known that I, :ALBERT A. stemmer,- a citizen of the United States, yresiding at Madison, in the county of Dane and State of Wisconsin, have invented `certainn 'ew and Vuseful Improvements in Lubricators, of whichv the following isI a specification, reference bey' ing had thereinr to the accompanying drawings. l n.

' This/invention relates to improvements 1n' force-feed lubricators,.partieularly ofthe type .radapted tofeed heavy lubricants under high pressures' to: the cylinders of: steamfengines andjfor similar purposes.

--Figure 1 isj'a view, partly side elevation and` partlyinsection, of a lubricator embodyf lng-my improvements. Fig. 2 is a sidey elevaj .i tionof 'the lubricator lookingF fromthe o'pposite side to that in Fig.v 1. f

It may-be of `any desired shape-or size. 2 indicates an opening at the '1 top thereof, and .3 indicates a ,cover for the same. *y .f 4 -11 is an openingi'ini'one of the walls of the reservoirl and lpreferabl nearthe bottom thereof. `y 5 indicates/a lock adaptedto fit rintosaid opening and provided with .fa flange 5.` 58L represents screws for securing the said flange to the Wall of the oil-reservoir.

; drawings I'have shown aY trainvof devicesfor imparting intermittent motionf'to thesaid shaft. This train consists of the ratchet-wheel 8o y 25,"seeured to the shaft, the pawl 26, adapted," to engage with the teeth o'n lthe engine, so as to receive oscillating motion therefrom..

32 is a strainer of wire mesh surrounding the openin between the oil-duct 7 and the interior of t e oil-reservoir.

It will be noted that the principal operative parts of my mechanism are located within the oil-reservoir, where they are Well lubricated and are protected from dirt, dust, and the elements and from injury due to the rough handling to which many of the engines, such as traction-engines upon which these lubricators are placed, are subjected.

The operation of the oil pumping and forcing devices will be readily understood. The eccentric 19 causes both a reci rocatory and oscillatory 'motionto be simuitaneously imparted to the plunger 17. On the upstroke of the said plunger the slot 17 therein is so turned as to establish communication between it and the interior of the oil-reservoir through the duct V7 and to cut off communication between the slot and the oil-delivery duct 8. During this stroke oil is therefore drawn into the vcylinder 6. On the downstroke of the plunger it is turned so as to cut off communication between the slot therein and the reservoir and to establish communication between the cylinder 6 and the oil-delivery duct 8 and to force the oil under pressure out through said duct.

What I claim is- 1 1. In a lubricator, the combination of an oil-reservoir having side, end, and bottom walls, a block having a vertically-arranged oil-cylinder therein, said block resting against the bottom wall of said oil-reservoir and detachably secured to one of the side walls of the oil-reservoir, a vertically-arranged plunger in said oil-cylinder, there being an oilinlet duct leading from the interior of said oil-cylinder to the interior of said reservoir and an oil-outlet duct leading outward from the interior af said oil-cylinder, and power. transmitting means arranged within said oilreservoir for actuating said plunger.

2. In a lubricator, the combination of an oil-reservoir, a block having a vertically-arranged oil-cylinder therein, said block being detachably connected to one of the vertical walls of said oil-reservoir, a plunger in said oil-cylinder, power-transmitting means within the oil-reservoir for actuating the ilunger, there being an oil-inlet duct leading rom the interior of said oil-cylinder to the interior of said reservoir, and an oil-outlet duct leading from the interior of said oil-cylinder to the exterior of the said oil-reservoir.

3. In a lubricator, the combination of an oil-reservoir, having a lateral opening through one of its vertical walls near the bottom thereof, a block extending throu h said opening into the interior of said oi -reservoir and detachably secured to said oil-reservoir with a Huid-tight joint, and having a hole therein arranged parallel to the axis of the reservoir and an outlet extending from said hole to the exterior of the said block, a plunger fitted to and adapted to operate in said hole, the power-shaft extending through said oil-reservoir and mounted in bearings in the Walls thereof, and means arranged between said bearings and connecting said shaft with said plunger adapted to impart a reciprocating motion to the latter.

In testimony whereof I affix my signature in presence of two Witnesses. 4
